Wing Skins
There has been a lot of recent discussion with skinning foam wings and vacumn pumps. I am not sure of your sources or procedure for building the skins, but wanted to share a great source.
Buy your skins from National Balsa, Code #1161048, 1/16" X 10" X 48" Blasa sheeting. Last cost was $5.45 sheet. This product is not on his web site, you have to ask for it in 2 oz weight. He must us alphatic glue when he assembles these as they sand great, without ridges.
